WILDLIFE IN THE FENS MARBLED WHITE In July and August the Marbled White is found mostly in the south of England but extends into southern Wales and up the east coast as far as Yorkshire. It often lives in colonies - sometimes in large numbers - where it prefers rough ground in and near woods - cliff tops and bill sides. It is a slow flier and easily caught. The colour varies from white to a bright pale yellow - and the usually creamy underside has bright olive green markings. The caterpillar is a pale pinky-green with darker stripes and feeds on grasses - mainly Sheep's Fescue Grass. The female is larger than the male. Wingspan approx. 1 7/8 - 2 1/4 inches.
